Plastics piping and ducting systems - Injection-moulded thermoplastics fittings - Methods for visually assessing the effects of heating (ISO 580:2005)
ISO 580:2005 specifies two methods for assessing the effects of heating on injection-moulded thermoplastics pipe fittings -- method A, using an air oven, and method B, using a liquid bath. In case of disagreement, method A is the reference method. ISO 580:2005 is applicable to cement-welded fittings as well as to flanged fittings and fittings incorporating elastomeric seals and to fittings consisting of the assembly of several moulded parts (e.g. union connectors). It is applicable to both pressure and non-pressure fittings.
Kunststoff-Rohrleitungs- und Schutzrohrsysteme- Spritzguss-Formstücke aus Thermoplasten - Verfahren für die visuelle Beurteilung der Einflüsse durch Warmlagerung (ISO 580:2005)
Diese Internationale Norm legt zwei Verfahren zur Beurteilung des Einflusses der Warmlagerung von Spritzguss Formstücken aus Thermoplasten fest - Verfahren A, unter Verwendung eines Wärmeschrankes mit Durchlüftung, und Verfahren B, unter Verwendung eines Flüssigkeitsbades. Bei Schiedsfällen ist Verfahren A das Referenzverfahren.
Diese Internationale Norm gilt sowohl für Klebefittings als auch für Formstücke aus Flanschen, Formstücke mit Elastomer Dichtringen sowie für Formstücke, die aus mehreren Spritzguss Teilen zusammengesetzt werden (z. B. Rohrverschraubungen). Sie ist auf Formstücke für Druckrohrleitungen und drucklose Rohrleitungen anwendbar.
Systèmes de canalisations et de gaines en plastiques - Raccords thermoplastiques moulés par injection - Méthodes d'essai pour estimer visuellement les effets de la chaleur (ISO 580:2005)
L'ISO 580:2005 spécifie deux méthodes d'essai, la méthode A qui utilise une étuve et la méthode B un bain liquide, pour estimer visuellement les effets de la chaleur sur des raccords de canalisations thermoplastiques moulés par injection. En cas de désaccord, la méthode A est utilisée comme méthode de référence.
L'ISO 580:2005 s'applique aux raccords à coller, y compris aux raccords à brides, aux raccords munis d'une bague d'étanchéité en élastomère et aux raccords constitués par l'assemblage de plusieurs éléments moulés (par exemple les raccords union). Elle s'applique à la fois aux raccords sous pression et aux raccords sans pression.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 580 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the
transport of fluids, Subcommittee SC 5, General properties of pipes, fittings and valves of plastic materials and
their accessories — Test methods and basic specifications.
This third edition cancels and replaces the second edition (ISO 580:1990), which has been technically revised.
ISO 580:2005(E)
Introduction
The test for determination of the resistance to heat according to the two test methods specified in this
International Standard is applicable for distinguishing between properly and improperly moulded
thermoplastics pipe fittings.
It can be used to
determine whether cold slugs (pieces of material that enter the mould at a temperature significantly lower
than the rest of the mass) or unfused areas are present,
reveal cavities and porosity,
determine the amount of moulded-in stress produced by the moulding process,
reveal contamination, and
show the integrity of the fusion line.
A stress-free part will generally have better properties and higher strength than parts with a higher degree of
residual stress and will generally be less reactive when exposed to chemicals. By placing moulded fittings in a
heated medium (air or liquid) at elevated temperature for a period of time dependant on their wall thickness, it
is possible to detect internal stress.
Since the stresses start to be released as soon as the material passes to the rubbery state, it is only
necessary to maintain the moulded pieces at a higher temperature for a defined period of time.
NOTE Injection-moulded fittings can be made by a number of techniques, whereby the material is injected into the
mould cavity. These include single- or multi-point injection, diaphragm gating and ring gating. The technique used in the
manufacture of mouldings will affect the way in which they are assessed.
